CALCULATING-MACHINE.

Specification of Letters Patent.

Patented June 4, 191%.

Application filed May 12, 1904. Serial No, 202631.

To all whom it may concern Be it known that l, Hanne C. Pincus, a citizen of the United Staten, residing at Indianapolis, Marion county, indiana, have invented certain nenY and useful lmprovep ments 1n Calcalating-Machines, of which illustrated and described, for--insta-ricami. LetterwPatent of the lmited States Nos.

tion is netto be understood as limited in ite` application to a Burroughs machine, inaa much as the same may be embodied in ealcu-.

lating machines of similar character. and used for similar "purpose-s.

The main object of my invention to provide means, controlled by the movements of the paper carriage, for eliminating or throwingout of action the adding` mechanism proper of the machine, with the result that at a certain position or positions of the carriage, as may be predetermined by -the operator, the addingv machine will be permitted to exercise all ita functions, that is the printing; and adding of an'iounts` or items, in the usual and vu ell known manner, and at a certain other position or positions of the carriage, the adding` feature or function of the machine will-bc thrown out. of action, but ivithout interference with its usual functions' of printing. .Tlie means which I have provided for thus throwing 'the adding function of the machine out lof action may be normally operative with re-A spect to the regular mechanisn'i of the machine and be rendered inoperative, or th'e reverse arrangement may be provided, that is, such means may be normally inoperative and bev rendered operative when desired, as

determined by the particular position of the paper carriage. I have herein illustrated both arrangements, but the former one `is now preferred.

The addiupl machine embodying my inven- I tion and as itis herein shown and described is therefore capable of printing in two or more colunms, one or more only of which columns are to be added, that. :is to say, the maehineisadapted to print on the eamehorizontal line, for example, a number or numbers not to be added, and then one or more neunte requiring` to be added. by the mabe either cross-addition `or'vert-ical addition,

quired to be added and then, in a Succetalinggoperation` printing on the Same horizontal line and, by one movement of the operating handle, tivo seta of amounts which are to be added. The machine is, therefore, adapted by repetitions of such operations to print and list a plurality of columns of numbers and amounts. The number of such columns is dependentl .simply upon the capacity or size of the paper carriage of any particular' machine.

in adding machine embodying my inventionis adapted for use in recording transactions or accouutings where a number or numbers are to be printed in connection with one or more amounts, all of which different claeses are to be printed and listed in succession (that is, Without printing and listing each set or class Separately), although only the amounts or items are to be added or accunnilated. rlphere is a considerable variety of accounting work Where such a, machine will find useful application and, for the Ypurpose of affording a. definite description and clear comprehension of my invention, I will explain it in connection with one of its many particular uses, that is, in railway car accountants work. AS is Well knowinvin such particular kind of Work, railroade keep accounts with each. other as to their respective cars, such accountslsetting forth Vthe numbers bf the cara, the number of days auch cars` have reapectively been on the tracks of the railroad making,r such account, and, i'n addition, the number of ,daye that the :are have respectively remained. on the tracks after the expiration as desired. In the present instance, the ma: chine is capable of printing a. number not re` t, nne,""\vhich addititm of said amounts rmay time limit, known in railroad iiarlai'ice as penalty days. lt is required, in this car accounting, that the number of the car, the

number of days on track and the number 0f penalty days shall be printed 1n successive arrangement and on the same hori- Zontal line, and that thel numbers oi the cars shall not, of course, be added, but that the other classes of items, that is the days, shall be independently added or accumulated. In the present instance, and as the machine is herein shown adjusted, l provideior printing and listing two sets of these three columns of numbers and added items on the same sheet of paper, making six columns altogether', but as hereinbefore stated the number of columns is dependent only upon the size er1/capacity of the movable paper carriage of any particular machine. AAgain3 in the present instance, I provide printing/of each of the numbers not requiring adding (the car numbers in the example mentioned) by one operation of the machine and for the printingoitl the two classes of the amounts or items requiring addition (the two classes representing days in the example mentioned) separately in the same horizontal line by a single but subsequent operation of the machine, and the saine is true'as to the totaling or subtotaling ot' the columns of these particular items representing days.

-To this end, the machine is in eli'ect split or separated into two adding machines acting` independently so far as printing, listing and adding are concerned.

he principal feature of my invention therefore comprises mechanism associated With an adding machine and controlled by lthe position and movement of a laterally iiioyable paper carriage for eliminating or throwing out of action the usual adding featurepf such machine, leaving such inachine, under, these conditions, to perforn'i its usual functions of printing, and, further more, my invention" relates to and comprises, in the present instance, certain mechanism associated with the movable paper carriage for securing, in automatic manner, both a horizontal feed of the carriage for columnar spacing and a vertical feed of the paper thereon at any predetermined time, or position of the carriage, in order to render the machine adaptable to specific or special requirements ot' different kinds o'lE accounting work, aswell as to render the machine as automatic as possible. Thus, besides controlling the action ot' the adding mechanism of the lmachine and thereby determining whether' the machine shall or shall not. add, the paper carriage is arranget'l and adapted to control both the columnar spacing and the line feed oi the platen, in a manner hereinafterniade apparent.

for the For the purpose of distinguishing the numbers which are to be added and those which are not to be, I will, throughout this specification, refer to the former class as numbers and to the latter class as amounts or items.

22, 23 and 24 views showing dillerent samples of the work done on my machine.

inasmuch as the Burroughs machine manufactured and as disclosed in said prior patents is weil known as to'both its construction and mode oi" operation,'and as my invention comprises mechanism additional to .such machine, a detailed description of the entire Burroughs machine is rendered unnecessary, and it will therefore suflice to describe only those parts which are associated or concerned more or less directly with my invention.

As usual, the key board has a' plurality of rows of keys 291, extending from front to rear otthe machine, there being, .in the present instance, eighty one keys on the keyboard, arranged in nine rows of nine keys each.' The nine keys in each row represent the nine digits and tlie'respeetive rows represent di'iiferent denominations iucreasiug from right to left. As herein shown, my machine is split or divided into two separate adding machines, `by omission of a certain part as hereinafter explained,

and to this end the rows of keys associated ica guishable from each other, as by contrasting branches 914a and 91-1" adapted to cooperate colors. In thepresent instance the right hand division of the machine comprises lire of the rows of keys and, as the keyl'ioard is now made, such particular rowsot keys are colored white, while the four remaining! rows of keys, comprised in the .lett hand division of the machine, are colored black. The keyboard is provided with the usual repeat key 203 to enable any number to be repeated without resetting; the proper vkeys on the keyboard, and also with the usual total key A265, controlling the operation of the printing mechanism to print a total, thereby enabling a total to be taken whenever desired by the operator.

The levers B, which correspond in number With the rows of keys, are hung upon the main rock shat'gttlthvltig. 9 and are each provided with the rearwardly extending sector-shaped arms olla carrying the usual movable type plates 618, and provided with forwardly and downwardly externling arms 611 opera-tively,connected with geartoothed racks 610. For a detailed .description of the ineans for controlling,` the movements of these racks, reference may be made to said prior Burroughs patents. 4

The series of racks 610 cooperate with a corresponding series; of addingwheel pinlions 916, to each of which is secured an adding or dial wheel 912. These pinions V- and adding wheels are mounted in a swinging frame consisting of the two arms C arranged atopposite sides of the machine and secured to a rock shaft 900 journaled in the frame thereof. In the usual operation of the Burroughs machine (except when totaling) this pinion frame is swung, bodily forward out of mesh with the racks G10 upon the forward rf fment of the operating handle 367 and the consequent downward movement of the particular racks; released, but such pinion traine will be swung,r into mesh with such racks upon the rearward movement of the operating handle and the consequent upward movement ot' the released racks, Withthe result that the pinions and adding wheels, cori'espondinbi` to the particular racks releasechwill be turned by such racks distances corresponding to the previous downward movement t-l'iereot.-

The swinging. of the pinion 'traine into and out of mesh with the racks (310 is controlled by the movements of the arm ill-'l and the three-armed lever 913, to which the former is pivoted at its rearward end. In

order to support the forward end ot this connected at its upper end to the bell crank 227 of the total keyl 2G5. The front end of the arm 914C has two divergingarms or with the pinion frame in the well known .a grand total, and when such key is kept depressed during' only the iorward movement of the operating; handle and released just prior to the rearward or return movement thereof, the macl'iine is caused to print a subtotal.

Upon the rock shaft S00, which is actuated by the operating` handle, 3137, is mounted. a three-armed lever 813, whose upwardly and forwardly extendingV arm 812% carries a pivoted wiper-block S21 adapted to coperate with the studs 961 and 961 on the rearwardly and forwardly exte'iulingi` arm ot the lever 913. The spring tends to swing the wiper block into alinenient with 'thevarm 8133, and in the position of the parts as indicated in Fig. 2 such spring holds the upper end of the wiper-block against the rear side oi the 'toi-ward stud 9G11. inasmuch as my added mechanism or attachments are directly associated with the old parts now being` describedl and atl'ect their usual or normal operation, l will explain such normal operation, which is as follows: lVhen the operating` handle is drawn toi'- wardly, the shaft 800 is rocked in an anticlockwise direction (Fig. 2), and the wiperblock consequently caused to engage the stud 961g. and force forwardly the depending,` arm of the lever {lli-l, with the result that the connecting,y lever ill/l, by the engagement. of its branch 'arm 914 with the, stud 958, swings the pinion frame C forwardly and the pinions out of gear with their racks G10,

so that the racks may d'esceinlwithout turning the pinions. (ln the rearward or return movement ot' the operating;v handle, the shaii't S00 is rocked back to normal position, and during' such back niovemcnt, the wiper block 821 will engage the other stud 961, and by thereby forcing the rearwardly extending arm ot the lever Slt-l upwardly, the lever 914 will be drawn back to norn'ial position and with it the pinion traine C because of the engagement of the notched end 914- with the stud 058 on such trame, with the result til at the pinions will be put in mesh with their racks and turned thereby distances correspondingi to theprevious downward movenient of the respective racks. During; the forward movement of the operating` handle the racks and the forward ends of the par.-

ticular levers B released through the noedium ot the keyboard andconneotions, dcscend distances determined by the value oft' the particular lieys operated, while the rearward ends of such levers aro raised so as to presentati the printing line the types Corresponding to the operated keys. At the end of such forward movement of the operating handle', the types are forced against' the platen, by means of strikers as described in said Burroughs patent, to effect the printing pf the amount represented by the operated eys.

In the foregoing description, I have -not taken into consideration the means provided in Burroughs machines for preventing thedepressing of I movement of the operating handle is begun, but the same will now be.described inasmuch as they are concerned with the operation of my attachment. These' means comprise the pivoted locking arm 828 having a spring 881 tending to force the upper end of sucharm forwardly and into the path of the stud 227 on the bell crank' 227 ofI the total key.l Normally, however, vthe arm 813*1 bears against the stud 858 ofthe lever 828 and thereby restrains the spring, with the result that normally 'tpe upper end of the arm 82S is held out of tic path of movement of the stud 858.jandffhe total key permitted to be. depressed. 'But on the first movement of the operating handle and consequent rear-,

This action is brought about by the succesthesc means, the total key is the total key after. the;

figure or figures making up the printed item.

sive tripping, from left to right, of latches 717, to 4which end such latches (excepting the outermdst one on the right hand side) have projecting lugs zZ to cause interference between the latches, whereby the tripping ,action .is communicated successively to releasollie hai'nniers,"causing a printing of the heures of those type plates corresponding to operated keys and a yprinting of ciphers by those levers whose keys have .not been operated. In the present instance these latchesI are similar in construction and operation to those already -explained as usual in the Bur roughs machine avith the exception that the said interference of latches is destroyed in suitable manner at one point., and to this end the lug fl of the sixth latch corresponding to the sixth row of keys counting from the right is removed or dispensed with, as shown in Fig. 8 herein. However, it will be obvious that the interruption of coperative relationship of latches might be at any other' point.

The result of th change just mentioned is to split or divide the machine into two machines or. divisions, capable of separate printing, listing and adding, whereby two separate items may be lset up on the keyboard of the machine and separately printed and added with one operation' of the operating handle. The effect of thus dispensing with the lug d on one ofthe latches will be quite evident for, aswill be understood, the tripping action of the latches of the left hand'division of the machine will not be communicated to the right hand division thereof, with the resultthat ciphers cannot be 'printed on the left of any figures printed by the right hand division of the machine. The machine shown therefore constitutes two separate adding machines assembled and associated together and operated in unison by an operating handle commomto both machines.

The paper carriage and platen roller 619 and their associated parts are,'in general, the same as those shown in said priorPike patent. The platen roller is mounted in the ends of a frame a which is arranged to swing on the carriage Z). This carriage travels on a track c formed at the upper end of a supplemental frame c extending from the machine frame and has a downward extension or framework Zi' upon which is mounted various devices forming parts of my new mechanism as hereinafter explained.

The longitudinal or transverse feed of the paper carriage will be rdescribed later on,

'inasmuchas it concerns more or 'less the new mechanism of the machine. The vertical paper feed or line spacing is also concerned with such new mechanism, but the main operating parts may nevertheless be vreferred to at this point. The platen roller at its left hand end has secured to it a ratchet 519, with which coperates a spring-pressed pawl 521 carried by a bell-crank shaped plate 526 hung upon the spindle of the platen roller. The pivotedplate 526 is connected by means of a link (Z to the arm of the bell crank e which is secured to the end of ldue longitudinal rock shaft c suitably mounted in the Swinging carriage frame. Rocking of the shaft e', in an automatic manner as hereinariel lset forth, causes the pawl 521 to advance the platen roller la line space, whose amount is determined by the particular point of attachment of the link d to the plate 526.

\Vith the exception of the suggested' change as regards the tripping of ,the latches, the machine above described is substantially the Burroughs .machine, after which description the operation, function and relation of the added parts, now to be explained, will be quite readily understood. For the purpose of distinguishing the new from the old parts contained within the case I havepin Figs. 2 and 9, shaded the new parts but left the old parts in simple outi .lollul ilumition iodieuled .in i Y The arm 813' of the three armed lever noodles line, while in Fig. l() I have shownsuch new parte by themselves.

Upon the rook Shaft 800 is hung,` or pivoted the lower end of a lever arm l whose body portion is substantially straight and Vertical and whose ends are both forwardlycurved or turned. i. he lower .end of this lever arm is piv'ted on the rock shaft 800 as described, while the upper end is slotted or bifureat'ed (foriconvenient assembling) to receive and engage a pin 2 on the inner side oi' the usual link i226 forming' one of the Connections assoeiated with the total lrey of a Bun j s machine. This pin has an enlarged head or flange 2a (Figs. 9 and l0) to pre- '\.'entlateral movement of the upper end of theleifer arm and thereby preserve its -enlemggenient with the pin. A portion of the trent edge oi the lever arm l ie so shaped or extenlled forward tnvardv its lower end as to present a bearingsurfaee or iuteri'ei ence tace l arranged to coperatie with other parte in amanner hereinafter explained. lt is apparentthat a rearward movement of the upper end ot1 the lever l will cause a corresponding rearward movement of the link i226 in the Same manner as the depression o the total key as indicated in llig. 9, which movement or dey'n'ew sion of the totelf liey'eonneetione serves to eliminate or throw out the addition fea ture or function o't' the machine. I'ilhls lever l i5 designed to be actuated, undereertain Comlitions by a moving' part of the regular machine, and in theA present instance this result is; accomplished in the following manner: livoted at one end at the point 27') on the left hand side oi the rearward portion of' tbe machine is asubstantially horizontal lever et. which extends t'mu'ardly al, one eide of the lever arm l and just beyond the iutermediate portion thereof.A The leverel oai-, ries at its forward end a pivoted and depending bell o anla shaped arm 5 from whose lower end there extends inwardly what if term an inler'ferinza stud '(3 berause of its in terterenee under certain eonditionfswvith the ope tingy parts in 'theniianner hereinafter. explained. 'ilus interijerulg Stud is ajrranged in close ,oroxin'xily to the bearing); sulface l and intersects its plane 'of moveuuut.

J ust vbetere the extreme end of the forward stroke oit` the handle and the consequent extreme end of the rearward Stroke 4oi" the arm 813 has been reached,l the vbloelr with suoli stud 958. ,lhe adding feature of the machine is thus eliminated or thrown'out ot' action in bothrvthe forward and rearward movements it-the operaiinghandle, so that the maohine may be employed for simply l listingr and ninting, without addition. Ae hereinbelore Iexplained in yrespect to the usual 'operation of a llurroughe` machine, the looking' arm 828 which is normally re-V strained from looking the total key in normal upward [msiti'om by means ofv the arm 813, kle rocked by its springi- '881 at the lirst movementy ot the operating' handle, but iuasluuli'h as the operation ol my attachment involve@l 'the depression of the total 11() hey. it becomes necessary, under such coudilions. to continue the restraint o'l this loclv lug arm. after the arm 813 has moved a 'ay from ile interfering position. For this purpose lY provide means control led bythe movomonts or the controlling lever 4. and arranfreifl lo engage the arm 828 when such lever 4 le ariuated. in the presentinstance, these means comprise a .substantially llorizontal looking' lever 5% huug or pivoted intern T120 mediate its length on the ebalt (300 andr piv- I,

Volally connor-ted at its-rearward end with a vertical link l) whore `lower end is, in turn, loivotally Connected io the controllingl lever le with the result that; the movements of'125 the lal'ler lever are .fommunif-:ded to `the looking loi/'er S. The oxtrenu, forward end ot" the lookingn lever is provided with an up- 'wardly turned hook l() which engl-ages an il/iwardly directed stud on the arm 828. This 139 stud by preference has an enlarged head or flange 11a, so that the hook is lheld into operative engagement with the stud.

When 'the interfering stud 6 is in operative relation with the lever l, as indicated in Fig. 9, this hook is laengagement with the stud 1l of the lever 828 and locks such lever againsttorward movement as to its upper end even when.v in the operation of the machine, the arm 813a has moved rearwardly. The result of this construction and lmechanism is operative or inoperative. To

this end (and referringto the particular construction of Fig. 2), the rearward end of the controllingr lever 4 is extended rearwardly through a. vertical slot 1167 in the rear Wall ot the case 1167 (Fig. 1G) of the machine parallel to the usual slotJ 1167b in which ordinarily works a paper toed lever such as that designated T in said'Pike patent but which in the present construction is occupied by a ditterent part, hereinafter described. Tn the present instance, for the sake of convenience in assembling` this rear end of the lever 4 is made of a separate piece which' is attached to the main portion of the lever in suitahle manner. and readily detaeh able at'will. 'lhis end of the controlling; lever is of irregular shape as seen in Fig. 11, the same connirising a forwardly extending portion 4 projectingr through said slot 1167, a right-angled portion or plate 4l extending laterally to the right just in rear ot the rear Wall ot' theniaehine ease, and connnisiingr also a depending portion or actuating; finger 4 whose lower end is curved rearwardly and slightly upwardly in order tocot'iperate with the movable paper carriace. ashercinatter explained. This tinfrcr isadaptcd to move or 'rocltin a` vertical plane and the movement thereof is communicated to the lever 4 and depending` arm 5 and its interfering stud tl, so as to raise and lower them.

Referring to Figs. 3, 4l. 5 and 7.v a lone narrow plate 12 is secured to the lower end of the depending extension bk of the carriage frame and arranged in a horizontal position. lThis plate. 12 is provided with a Slot 12, extending almostV its entire length. to receive the clamping screws 12" ot thtl proJections or cams 13, which depend from ytherein the lower edge of the plate 12 in position to operate the controlling lever finger 4 when the carriage is moved. As herein shown, (Fig. l) each cam has two guide pins 13L rcccivcd b v the slot 12L and arranged to slide in the adjusting; operation. .screw 13" serves to lock the cam in adjusted position. ln the present instance, there are two ot these cams which will enable columns of different classes oi numbers and values to Ihe printed on a single sheet of paper, buty it will be understood that a single cam may be employed or brought into operative relation in case either two or three columns ot' such different clas-es of numbers and amounts or values arc to be printed, and also thatthe number ol such cams may be increased accordingr to desired increased capacity ot the machine or increased number ot` columns l The cams are adjustable longitudinally ot the slot of the plate 1Q to any desired position-therein, but in practice such cams are adjusted to certain points along the plate 1Q- eorresponding to ditterent stop positions of the paper carriage as determined by a tabu# latin; rail hereinafter described` with the result that when veither one of the cams is in position to depress the actuating finger 4Q as shown -in Fig. 3. the paper carriage will be in proper position to receive an iinpression or impressions from the printing mechanism in a certain column or columns. 'lhese camel have sloping; edges or sides which engage the tinfrcr l. which rides thereupon in -both directions ot travel ot' the paper carriage. and (referringto the structure exhibited in l"i .)rlhc arrangement isV and Aforce. it "downward to its tull extent.

thereby rendering my attachment inoperative and restoring' the machine toits usual and normal condition-as to the pcrlornmnce of its addingr function. llet'crring' to the construction now beiner described, when the finger #lc is in its uppermost position bearing' against thc lower edge ot' thc plate 12: my attachment or mcchanism'is in operative relation in respect to the mechanism ol" the adding machinc, 'The construction is therelore such that thc attachment. is alternately rendered operative oninopcrative by thc movements ot' thc paper carriage'.

'lhctabulation` device comprises. in the present instance. a tabulatinfr bar 14 arranged on therear side ol the supporting iramc c'. on which tbc carriage truclif' is formed, and in tact .it one side ot' such track as indicated in Fig. 1;). is illustrated-in detail in Fig. lt). this bar. which is prefer# ably detachable. has a series 'of notehesvl between which the edges of the bar preferllt) left of the machine viewed troni the oper` ably incline upwardly from the right to the ators position, inorderfto enable the eooperating catch or locking dog` to engage the -notches with more certainty.

This inelin ing' of. the edges of the bar forms a Seinen of shoulders 14h constituting one side wall of the notches, which Shoulders the l'ofting.

-cated through the arms 513 and 19 to the short rock shaft 1S and thus to the arm 20. The described arrangementis such that the wiper plate 22 does lnot more upward to perform its stated function until the beginning of the return or rearward stroke of the operating handle, so thatA .the carriage will be permitted to move only after the machine has done the printing. Furthermore, it will be understood. that any desired number of these tripping arms 23 may be employed aecording to the capacity or width of any particular paper carriage and also according to the particular number of columns to be printed on any single sheet of paper. Ilowever, in the present instance, two of such arms are shown for the purpose of doing the class of accounting work in connect-ion with which my invention is being explained, although it will be understood that my invention is not limited to the employment of any particular number of such arms.

When two sets, for instance, of columlr.- of -igures are being printed and listed, l prefer to provide, on the rock shaft 15, a stop arm or finger 24 (Fig. 18) which is ad justablysecured on said shaft by means ot' a set screw 24. This stop finger is arranged on the shaft toward the right hand end thereof viewed from the operators position and is adapted to eoperate with a rearwardly projecting stop pin 111C on the tabulating bar 14. This pin is so positioned that it will stop or limit movement of the paper carriage to the right, to a point slightly beyond the position oceupied'by the carriage when ready to receive the imprint of the first column of the second set 'of numbers (that is the fourth column in the example of Fig. 22). By-use of' the knob 15C the oper; ator is enabled to shift the carriage by hand to'its full extent. to the riuht for the work on the left hand side of thel paper. rlhis stop arm possesses, under the present construction, a second function, in that it is adapted to bear against the lower edge of,

the transverse bar b2 (Fig, 18) of the carriage frame and the adjustment. of the arm on its rock shaft is such that it will prevent the locking dog 16 from entering any ol" the notches of the taliulating bar but permit suth dog to contact anyone of the shoulders 14% thereof and thereby stop the carriage iii different columnar positions. This ar! rangement enables the carriage to -be returned to initial position by simply shifting the carriage back without having to firstunlo'ck it.

According to the construction herein shown, the stop pin 14e stops or limits the movement pf the paper carriage to the right its full length of travehby contact of the middle bearing lugs 15b thereagainst, when the operator shifts or restores the carriage to the right to original or initial position, ready for the neXt line of numbers or items.

After the rst set of vcolumns (three in the present instance), has been printed and in order that the same may be continued on the right hand side of the sheet of paper or a new set of columns started, the operator, besides setting back the paper to the proper starting line, rocks the, shaft. 15 more than ordinarily so as to swing the stop finger or arm 24 below and around on the other side of the stop pin, whereupon the locking dog 1G strikes against the third shoulder on the bar, with the result that the stop fin-- ger 24 will now be positioned on the left hand side of the stoppin 14 andwill, by its contact with such pin, therefore serve to limit the required movement or feed of the paper -carriage to the right. duringthe printing ot' the said second set of columns. There is a slight play or movement between this position of the carriage as determined by the pin 14 and finger 24 and its position as detern'lined by the third notch or shoulder of the tabulating bar, so that'thc operator may return the carriage to the right until stopped as explained and then upon releasingr the carriage and after a slight return movement of the same, the locking dog will engage the third shoulder and hold the carriage-in position for receiving the impression in the first column of said second set.

The vertical paper feed is likewise automatic in that'it is controlled by the moving parts of the machine, and in fact by the particular position of the paper carriage, and to this end the feed arm 2l, already referredtO, is adapted to aetuate the paper' feeddevices hereiubefore described. 'l`l e longitudinal rock shaft c', hereinbeforc referred to, 'is provided with one or more feed lingers 2f which are sleeved onto the shaft and arranged for both longitudinal and rotarial adjustment, each linger being-secured Vin adjusted position by a setscrew 25. 'Each finger is provid-ed with a laterally projecting stud 25" against which the feed arm 21 bears when positioned in the path of movement thereof, with-the result that in the forward movement of the opera ting handle and the consequent rearward movement of the feed arm 21, the particular feed finger 25 presented tosuch feed arm will be rocked rearwardly, thereby rocking the shaft e and shifting the pawl 521 forwardly, so that leo
